Pseudomonas aeruginosa outbreak in a neonatal intensive care unit: a possible link to contaminated hand lotion
1Infection Control, St. Vincent Hospital, Green Bay, Wisconsin 54307-3508, USA.
Abstract:
This article describes a prolonged outbreak of Pseudomonas aeruginosa. The attack rate of this outbreak was 8.5%, with no associated mortality. Hand lotion contaminated with P. aeruginosa was implicated in the transmission of organisms; removal of this hand lotion ended the outbreak. Contaminated hand lotion applied to clean hands of health care workers may have led to direct inoculation of infants at high risk for infection.
Insights
A prolonged outbreak of Pseudomonas aeruginosa (P. aeruginosa) in infants was linked to contaminated hand lotion. Removing the lotion stopped the outbreak, highlighting a critical infection control issue.
Area of Science:
- Infectious Diseases
- Public Health
- Microbiology
Background:
- Nosocomial outbreaks pose significant risks to vulnerable populations, particularly infants in healthcare settings.
- Pseudomonas aeruginosa is an opportunistic pathogen frequently associated with healthcare-associated infections.
- Maintaining stringent infection control practices is crucial to prevent the spread of multidrug-resistant organisms.
Purpose of the Study:
- To describe a prolonged outbreak of Pseudomonas aeruginosa.
- To identify the source and transmission route of the P. aeruginosa outbreak.
- To evaluate the effectiveness of interventions in controlling the outbreak.
Main Methods:
- Epidemiological investigation to determine the attack rate and identify risk factors.
- Microbiological analysis to identify the causative agent and its source.
- Intervention assessment through the removal of the implicated product.
Main Results:
- A prolonged outbreak of Pseudomonas aeruginosa occurred with an 8.5% attack rate.
- No mortality was associated with this specific outbreak.
- Contaminated hand lotion was identified as the source of P. aeruginosa transmission.
- Removal of the contaminated hand lotion successfully terminated the outbreak.
Conclusions:
- Contaminated hand lotion served as a vehicle for P. aeruginosa transmission to high-risk infants.
- Healthcare worker hand hygiene and product safety are critical for preventing infant infections.
- Prompt identification and removal of contaminated products are essential for outbreak control.
